INSTALLATION

Window wiper kits in the WW57 Series are designed to operate with an AC voltage to turn
on the wiper. However, the kits must be modified to use +5 to +10 VDC to turn on the wiper
when the kits are used with Pelco’s receivers.

If you are going to use a Pelco receiver, proceed to the
tion.

If you are going to use equipment that provides AC power to control the wiper, proceed to
the

Window Wiper Kit Installation

section.

WINDOW WIPER KIT MODIFICATION

Modify your wiper kit if it is to be operated from any of the following Pelco receivers:

CX9000 Series
WX8000 Series
LRD41 Series
ERD97P21-U with the ERD97P-AUX option board

This modification only changes the voltage that is required to turn on the wiper. The wiper
motor still requires AC voltage (refer to Figure 1).

To modify a kit:

1. Remove the circuit board cover from the wiper motor/control assembly and remove the
circuit board (PCB9000275 Rev. E). Refer to Figure 10 for parts locations.

Refer to Figure 2 for steps 2-5.

2. Remove diodes D1 through D6.

3. Replace resistor R2 with a 1/4-watt 470-ohm resistor.

4. Remove capacitor C3.

5. Connect an 18-inch (45.72 cm) length of 22-gauge green wire to the hole in the circuit
board for the anode of D3.

6. Turn the circuit board over and cut the trace as shown in Figure 3.

Figure 4 shows schematically the changes that were made in steps 2-7.

7. Reinstall the circuit board in the wiper motor/control assembly and reconnect the wir­ing. Refer to Figure 7.
